Fuse blown
module
Bit pattern in units of
16 points, indicating
the modules whose
fuses have blown
0: No blown fuse
1: Blown fuse present
• The numbers of output modules whose fuses have blown are
input as a bit pattern (in units of 16 points).
(If the module numbers are set by parameter, the parameter-set
numbers are stored.)
• Also detects blown fuse condition at remote station output
modules

• When the power is turned on, the module numbers of the I/O
modules whose information differs from the registered I/O
module information are set in this register (in units of 16 points).
(If the I/O numbers are set by parameter, the parameter-set
numbers are stored.)
